Smoking calms me down. It's enjoyable. I don't want politicians deciding what is exciting in my life.

Photographs aren't accounts of scrutiny. The shutter is open for a fraction of a second.

Shadows sometimes people don't see shadows. The Chinese of course never paint them in pictures, oriental art never deals with shadow. But I noticed these shadows and I knew it meant it was sunny.

I had always planned to make a large painting of the early spring, when the first leaves are at the bottom of the trees, and they seem to float in space in a wonderful way. But the arrival of spring can't be done in one picture.

The photograph isn't good enough. It's not real enough.

Television is becoming a collage - there are so many channels that you move through them making a collage yourself. In that sense, everyone sees something a bit different.

The mind is the limit. As long as the mind can envision the fact that you can do something, you can do it, as long as you really believe 100 percent.

You had to be aware that I saw that photography was a mere episode in the history of the optical projection and when the chemicals ended, meaning the picture was fixed by chemicals, we were in a new era.

Art has to move you and design does not, unless it's a good design for a bus.

What an artist is trying to do for people is bring them closer to something, because of course art is about sharing. You wouldn't be an artist unless you wanted to share an experience, a thought.

Laugh a lot. It clears the lungs.

What I didn't know was I was deeply attracted to the big space.

And then I went round the corner and there's a Van Gogh portrait, and you just think, well, this is another level. A higher level, actually. I love the Sargent, but it's not the level of Van Gogh.

I was aware that the teaching of drawing was being stopped almost 30 years ago. And I always said, 'The teaching of drawing is the teaching of looking.' A lot of people don't look very hard.

When you are older, you realise that everything else is just nothing compared to painting and drawing.

Cubism was an attack on the perspective that had been known and used for 500 years. It was the first big, big change. It confused people: they said, 'Things don't look like that!'

Like people, trees are all individuals.

On the iPhone I tended to draw with my thumb. Whereas the moment I got to the iPad, I found myself using every finger.
